Furuno TZT 10xl Looses bottom over ~11 knots

Hello,

I’m a happy new user of the Furuno system. My setup is:

Furuno TZT10XL powered by a dedicated 100Ah lithium battery

1 kW in-hull Airmar M135M transducer

Installed on a 19 ft RIB

During my first trip I noticed an issue: I lose bottom reading at speeds above approximately 11 knots, even in shallow water (around 20 ft).

When drifting or moving slowly, everything works perfectly and the detection is excellent. I can clearly read the bottom and see great detail in depths of up to 400 ft.

Previously, I was using a Lowrance HDS with the same transducer setup, and it was able to maintain bottom lock at 25 knots in depths over 300 ft.

Because I’m new to Furuno systems, I believe I probably need to fine-tune the MFD sonar settings.

Could someone help me with the recommended setup for saltwater fishing?

Thank you in advance for your help.
